Document/script creating new VMs
Here's what I came up with using the official Ubuntu 20.04 cloud image as a starting point and cloud-init to add our SSH keys to the ubuntu user and set up Zerotier, using virt-install. I created a script that takes a VM name as an argument. We probably want to add proper options parsing for the disk size, number of CPU, etc
